On release button doesnt work in cs3 but does in flash 8


I have created a flash file in cs3 with a button having the following code:

on (release) {

when i publish and save the file as cs3 and open the swf or html file, the on release button doesnt work.

If i then publish and save the cs3 flash file as flash 8, the button then works when i open the swf and html files.

Why is this? Why doesnt the on release button work on cs3 files?

Please help :slight_smile:
